Q.Will last year’s lobelia flower this year?
I planted some lobelia last year and they flowered for months throughout the summer. Now we are heading into spring and as the winter wasn’t cold, is it possible for them to flower again this year, as the plants are still nice and green and bushy?
How interesting. Your plant may well flower again. And you may have a biennial variety. So keep taking care of it, and let us know what happens. You may enjoy this article on lobelia: https://www.gardeningknowhow.com/ornamental/flowers/lobelia/lobelia.htm
